Modal Analysis Using Operating Modal Identification Method
Chinese Journal of Aeronautics, 2004 AbstractSometimes it is very difficult for some large scale operating structures to measure the input forces. Modal parameters must be estimated on response only. A poly-reference time domain operating modal identification complex exponential method is presented since cross-correlation functions have the same form as impulse response functions.

Modal Indicators for Operational Modal Identification
, 2001 Modal validation is of paramount importance for all two-stage time domain modal identification algorithms. However, due to a higher noise/signal ratio in operational/ambient modal analysis, being able to determine the right model order and to distinguish between structural modes and computational modes become more significant than in traditional modal ...
